javascript - OpenEMM 调用不存在的 logon.do 方法

Question

在 Centos 6 服务器上运行 Tomcat 8.0 -- 尝试安装 OpenEMM。

当我尝试从 Tomcat 的索引页面访问登录页面时，出现 404。我发现 login.jsp 只是重定向到 login.do?action=0。但是，logon.jsp 文件中没有列出 .do 例程。直接访问 logon.jsp 文件会返回以下内容:

type Exception report

message An exception occurred processing JSP page /logon.jsp at line 37

description The server encountered an internal error that prevented it from fulfilling this request.

exception

第 37 行是这样的(必须删除 html 括号):

title bean:message key="logon.title" title

当我注释掉 bean:message 时，程序执行到第 63 行，即:

html:form action="/logon"

我有点头疼。有人可以为此提供一些帮助吗？

这里的问题是我使用的 Tomcat 版本。 OpenEMM 2013 需要 Tomcat 6。一旦我删除了 Tomcat 8 并安装了 Tomcat 6，错误就停止了。
